We estimated the growth of Jack mackerel (Trachurus murphyi) using increments daily growth, otolith weight and annual ring reading in sagittal otoliths. The micro-increments were used to fit density radius (n = 4481) then estimate age individual days. parameters von Bertalannfy equation were: maximum theoretical fork length, FL∞ 75 cm; coefficient, K 0.16 year-1; at which fish length is zero, t...

We give a linear time algorithm which, given a simply connected gure of the plane divided into cells, whose boundary is crossed by some colored inputs and outputs, produces non-intersecting directed ow lines which match inputs and outputs according to the colors, in such a way that each edge of any cell is crossed by at most one line. The main tool is the notion of height function, previously i...

Results are reported for a molecular dynamics simulation study of a exible model mesogen composed of seven tangential spheres. We follow thèrattling spheres' method by which bonded atoms are constrained to lie within narrow potential wells. The dynamics of the system is that of a hard sphere uid with added constraints. The phase diagram of our model system is calculated as a function of density...

We present a branch and cut algorithm that yields in nite time, a globally -optimal solution (with respect to feasibility and optimality) of the nonconvex quadratically constrained quadratic programming problem. The idea is to estimate all quadratic terms by successive linearizations within a branching tree using Reformulation-Linearization Techniques (RLT). To do so, four classes of linearizat...

We consider the k-center problem, in which the centers are constrained to lie on two axis-parallel lines. Given a set of n weighted points in the plane, which are sorted according to their x-coordinates, we show how to test in O(n logn) time if k piercing points placed on two lines, parallel to the x-axis, can pierce all the disks of different radii centered at the n given points. This leads to...

This paper studies the potential for liquidity crises and their impact on the course of monetary and exchange rate policies in a microfounded general equilibrium dynamic model in the tradition of Diamond and Dybvig (1983) and Chang and Velasco (2000). We produce a small open economy pure exchange overlapping generations model with random relocation along the lines of Smith (2002). The combinati...

background: the global prevalence of overweight and obesity had risen in recent decades, and obesity is taken into consideration as a public health concern and a major risk factor of common chronic disease. the objective of the present study was to estimate the prevalence of overweight and obesity and to identify its underlying factors among children 2-6 yr of age in fars province, southern ira...

Generating timetables is a cumbersome and time consuming task, but programs developed to solve them are usually meant for a particular organisation and can not be easily adapted. Constraint Logic Programming, the result of generalizing Logic Programming uniication to constraint solving over a computation domain, aim at expressing constrained decision problems declaratively, and still solve them...

The knowledge of Arctic Sea ice coverage is particular importance in studies climate change. This study develops a new sea classification approach based on machine learning (ML) classifiers through analyzing spaceborne GNSS-R features derived from the TechDemoSat-1 (TDS-1) data collected over open water (OW), first-year (FYI), and multi-year (MYI). A total eight extracted observables five month...
